For as long as you're subscribed to the service, you can swap out any of those five titles for new ones at the end of each month, or keep playing your favourites. All owners of HTC’s headset, the Vive, will get a free one-month trial of the service, which launches with more than 50 games and experiences.

With VR titles growing rapidly in quantity but not necessarily in quality, this could be a great way to put a range of experiences in the hands of early adopters to solidify their enthusiasm for the platform. President Rikard Steiber told Variety that HTC "see it as a very important promotional tool".

Though Steam is still the leading store for VR games on PC, with about 1,600 titles available there for the Vive, HTC's Viveport app store hosts much of the non-gaming content in VR. This content can also be used on the rival headset Oculus Rift.

To celebrate the Vive’s first birthday today, HTC is also giving a temporary £100/$100 discount of the system to new buyers, and action game compendium Arcade Saga (normally £13.93/$19.99) will be free to download.
